摘要

我们通过21 cm功率谱研究了相互作用和非相互作用三次伽利略模型与\(\Lambda \) CDM模型偏差的可探测性。我们表明，像即将到来的SKA1-mid这样的干涉观测可以检测到相互作用和非相互作用的立方伽利略模型与\(\Lambda \) CDM模型的偏差，这取决于参数值。

21-cm power spectrum in interacting cubic Galileon model

We study detectability of the deviation in interacting and non-interacting cubic Galileon models from the \(\Lambda \)CDM model through the 21-cm power spectrum. We show that the interferometric observations like the upcoming SKA1-mid can detect the deviations in both interacting and non-interacting cubic Galileon model from the \(\Lambda \)CDM model depending on the parameter values.
